How hard is Kirby Mass Attack?

My nephew loves Kirby but he's only 7 so I was wondering if he can handle it. If it's as hard as Canvas Curse I'm pretty sure he can't.

I thought it was harder than canvas curse. Squeak Squad would probably be the best for him.

Either Squeak or Super Star Ultra. If he/she insists on touch controls go with Canvas Curse, Mass Attack has a slightly higher learning curve.
